PISTON KIT 89-95 RM250 67.00 B, WOSSNER 8022DB SUZUKI MX

The Wossner 8022DB piston with a 67.01mm bore (66.95mm actual size) is engineered for high performance and durability, fitting Suzuki RM250 (1989-1995) and RMX250 (1993-1995) models. Forged in Germany, this piston is designed to optimise heat transfer from the combustion chamber to the cylinder walls. Its elliptical shape ensures uniform bearing surfaces during heat expansion, preventing localised pressure and piston collapse.
